METALLIC TIE.

Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed October 21, 1914. Serial No. 867,760.

To all 'whom t may concern Beit known that I, GEORGE F. BROCKWAY, a citizen of the United States, and a resident of Eden township, in the county of Fayette and State of Iowa, havemade certain new and useful Improvements in Metallic Ties, of which the following is a specication.

This invention relates to improvements in metallic ties for railways, and more particularly to one of the hollow metallic shell type.

One object of the invention is to improve generally, and enhance the utility of a rail tie such as disclosed in my former Patent No. 1,103,652.

A further object is to so arrange and con- 1 struct a hollow metallic tie that it will embody a minimum amount of material and 'view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention'.

In the drawings accompanying this speci- Yication and forming a part thereof, a preferable form of my invention is illustrated in which Figure 1 is a partial view in side elevation of my improved metallic tie. Fig. 2 is a sectional view taken on the line 22 of Fig. 1. Fig. 3 is a top plan view of the foregoing. Fig. 4 is a top plan view of the shell or body with the cover removed. Fig. 5 is a fragmental view of a sideof the shell with the tongues in an unbent condition. Fig. 6 is a view in cross section illustrating a modified form of truss bar.

Referring to the drawings, in which similar reference numerals designate correspondingparts throughout the several views, the tieincludes a metallic body 6 formed with the bottom plate 7. and side walls 8. Atop or cover plate completes the hollow shell-like.

formation.

The top and bottom plates are provided with the longitudinal and outwardly extending ribs l0, which strengthen the shell and also define the internal grooves 1l.

A truss bar 12 composed of one or more webs is positioned with its upper and lower edges within the internal rib dened grooves and braces the tie against vertical flexing or buckling. The side walls of the body are provided with spaced slots 14; arranged in pairs, so as to define a series of alternating wide and narrow tongues 15 and 16. The top plate is also provided with spaced slots defining a plurality of tongues 13 with the alternating tongues 13 fitting between and coacting with the tongues 15 to hold and securely lock the cover and bottom portion in rigid relation and with the intermediate tongues 13 bent inwardly to define ledges upon which the tongues 15 rest and which extend down against the side walls-of the metallic body 6 and thus strengthen the entire structure.

The truss bar divides the hollow shell into two longitudinal compartments in which are disposed the bracing strips 17, the same being formed of thin metal placed on edge and bent to form continuous and forwardly progressing loops of sinuous contour. 'Ihe loops alternatingly contact with the side walls of the body and centrally disposed trussbar to which latter they are rigidly secured by the rivets or allied means such l as welding, etc., 19. The outer extremities of these distichous loops are securely anchored in place by the tongues 16, which are bent thereover, as clearly illustrated in Fig. 2.

A U-bolt 24 extends through and is positioned substantially central of the tie, and securely locks the cover plate to the tie body at this point, thus supplementing the holding action of the interlocking tongues. In order that the tie may successfully withstand the large local pressure at the extremities, the bracing strips are thickened or doubled at these localities and above which the cushion blocks 27 and rail 28 are positioned. The rail and accessory clamping parts may partake of any desired form and are held securely in place by means of the U-bolts 25, which pass through suitable apertures 26 provided in the tie. The modied form in addition to bracing the cover plate, adds materially to the transverse or lateral strength of the entire tie, coacting with the bracing strips 17 in this respect. Y

Having now fully described my invention what IV claim is l. A'metallic tie comprising a body including side walls, a central web, and a sinuous bracingV strip anchored to said web and side wall.

2. A tie comprising a body including side walls, a longitudinal truss bar, and a sinu ous bracing strip alternatingly contactingV with and anchored to said truss bar and body side walls. Y

3. A metallic tie comprising a body including side walls, a longitudinal centrally disposed truss bar disposed therein, and a illustrated in Fig. 6A includes the cross-shaped truss bar l2 which t 5. A metalli'ctie comprising a bodyand cover plate with overlapping and interlock? Y ing tongues, said body-and cover plate provided with outwardly projecting longitudilongitudinally of said body with the yedges Ythereof disposed within the internal ribdeined grooves, sinuous bracing strips arranged upon opposite sides of said truss bar, secured thereto, and extending to the side Walls of said body, said body provided with spaced tongues projecting over said bracing strips and lockingthe same in rigid relation with respect thereto.

6. A vmetallic tie comprising ka hollow shell including body and coverplates with interlocking tongues, a vertical truss bar extending longitudinally of said shell anch arranged centrally thereof, Vand distichous sinuous bracing strips with thickened end nally extending ribs, a truss bar extending portions alternatingly contactingwith and anchored to said truss bar and shell vside walls; 7. A metallic tie comprising a hollow shell including interlocking body and cover plates,A f

a vertical trussbar extending longitudinally oit' said shell'and arranged centrally thereof and secured to `said body and cover plates,y

said truss bar provided with distichous for` wardly projecting continuous loopsanchored thereto contacting with the side walls of said bodyV and held rigidV with respect thereto. Y
